Related Applications This application is a divisional of Australian Patent Application No. 2009201239 10 the subject matter of which is incorporated herein in its entirety by cross-reference. Related Art Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field. 15 An electrophotographic image-forming device has a toner cartridge storing developer used for forming an image, and such a toner cartridge can be replaced by a user. Some toner cartridges are configured not to allow developer to leak when the toner cartridge is not attached to an image-forming device. For example, a toner cartridge disclosed by JP-A-2005-134452 has a shutter for a 20 toner port out of which toner flows. When the toner cartridge is not attached to an image-forming device, a shutter covers a toner port so that toner does not leak from the toner port. When the toner cartridge is inserted into an image-forming device, the shutter comes into contact with a member inside the image-forming device and is accordingly fixed in place. If the toner cartridge is further inserted, the shutter remains 25 fixed in place, while the toner cartridge body is moved into the image-forming device; as a result, a toner port of the toner cartridge is exposed. The toner port faces a developer path for transporting developer to a developing device. Developer flows out of the toner port, and reaches the developing device via a toner supply device. The present invention, at least in a preferred embodiment, provides a technique 30 for preventing developer stored in a container, which is being inserted into a device, from flowing anywhere other than into a developer path.

Automatic sheet feeding device 201 is a device for conveying documents onto platen 10 glass 202, which conveys documents placed on the device onto platen glass one by one. Reading unit 203 is a device for reading an image of a document placed on platen glass 202, which irradiates light to a document placed on platen glass 202, and converts light reflected by the document into electrical signals using a photoelectric conversion element. Reading unit 203 generates, on the basis of the electrical signals, image data 15 representing images of the document of Y, M, C, and K, and outputs the image data to image-forming unit 400. Sheet-feeding unit 300 includes plural sheet storage units 301 for storing sheets and plural transport rolls 302 for transporting a sheet, which transport a sheet stored in sheet-storage unit 301 to image-forming unit 400. 20 Image-forming unit 400 includes a photoreceptor that rotates in the direction of arrow a of Fig. 1, and on which an electrostatic latent image is formed, for each color of Y, M, C, and K (photoreceptors 401Y, 401M, 401C, and 401K). Image-forming unit 400 also includes charging devices 402Y, 402M, 402C, and 402K for charging a photoreceptor, and exposure devices 403Y, 403M, 403C, and 403K 25 for emitting laser light to a photoreceptor on the basis of provided image data, thereby forming an electrostatic latent image according to the image data on the photoreceptor. Image-forming unit 400 also includes developing devices 404Y, 404M, 404C, and 404K for developing an electrostatic latent image formed on a photoreceptor, using supplies such as toner, and toner cartridges IOOY (which stores toner of yellow), lOOM 30 (which stores toner of magenta), 1OOC (which stores toner of cyan), and lOOK (which stores toner of black) which are examples of a container storing toner to be used in developing devices 404Y, 404M, 404C, and 404K.

-10 Toner cartridges 1 OOY, I OOM, 1 OOC, and 100K are attached to toner cartridge docking units 150Y, 150M, 150C, and 150K which are provided for each toner cartridge, respectively, and toner stored in each toner cartridge is transported to developing device 404Y, 404M, 404C, or 404K via a toner path (not shown) connecting 5 a toner cartridge docking unit and a developing device. Image-forming unit 400 also includes: intermediate transfer belt 406 hung on back-up roll 409 and driving roll 410 and kept tense, that rotates in the direction of arrow b of Fig. 1 while contacting photoreceptors 401Y, 401M, 401C, and 401K; first transfer rolls 407Y, 407M, 407C, and 407K that face photoreceptors 401Y, 401M, 401C, 10 and 401 K, respectively, via intermediate transfer belt 406, and transfer a toner image formed on a peripheral surface of a photoreceptor to intermediate transfer belt 406; second transfer roll 408 that faces back-up roll 409 via intermediate transfer belt 406, and transfers a toner image formed on intermediate transfer belt 406 to a sheet; and fixing device 111 that applies heat and pressure to a toner imaged transferred to a sheet, 15 thereby fixing the toner image on the sheet. (Operation of Image-Forming Device 1) When a document is reproduced in image-forming device 1, a document placed on automatic sheet feeding device 201 is transported onto a surface of platen glass 202. Reading device 203 reads an image of the document placed on platen glass 202, 20 generates image data representing the read image for each color of Y, M, C, and K, and sends the generated pieces of image data to image-forming unit 400. Image-forming unit 400 causes each developing device to charge a corresponding photoreceptor, and sends the provided pieces of image data to corresponding developing devices. Each developing device emits laser light to a 25 corresponding photoreceptor in accordance with provided image data, thereby forming an electrostatic latent image corresponding to an image of color of Y, M, C, or K on the photoreceptor. Subsequently, toner provided from a toner cartridge to a developing device is provided from the developing device to a photoreceptor, and in each photoreceptor, the 30 electrostatic latent image is developed so that a toner image is formed on the surface of the photoreceptor. The toner image is transferred to intermediate transfer belt 406 by a first transfer roll corresponding to a photoreceptor.

- 11 Subsequently, image-forming unit 400 causes intermediate transfer belt 406 to rotate so that the toner image transferred onto intermediate transfer belt 406 reaches a position at which second transfer roll 408 is located. At this position, a sheet transported from sheet storage unit 301 by transport rolls 302 is transported into a space between 5 second transfer roll 408 and intermediate transfer belt 406, and the toner image transferred onto intermediate transfer belt 406 is transferred to the sheet by second transfer roll 408 and back-up roll 409. Subsequently, the sheet with the toner image is transported into fixing device 411, and the toner image is fixed by fixing device 411, and the sheet is thereafter ejected from image-forming device 1. 10 As described above, in image-forming device 1, toner stored in a toner cartridge is used to form an image on a sheet, and if toner stored in a toner cartridge dries up, it is necessary to remove the toner cartridge with no toner from image-forming unit 400, and attach a new toner cartridge to image-forming unit 400. Now, an operation of attaching and removing of a toner cartridge, and a toner 15 cartridge and a toner cartridge docking unit according to the present exemplary embodiment will be described. (Configuration of Toner Cartridge and Toner Cartridge Docking Unit) A toner cartridge and a toner cartridge docking unit according to the present exemplary embodiment will be described. Please note that since the configurations of 20 toner cartridges 1OY, lOOM, IOOC, and lOOK are identical with each other, and the configurations of toner cartridge docking units 150Y, 150M, 150C, and 150K are identical with each other, as an example, the configurations of only toner cartridge I OOY and toner cartridge docking unit 150Y will be described, and a description relating to the configurations of the other toner cartridges and the other toner cartridge docking units 25 will be omitted. (Configuration of Toner Cartridge I OOY) Fig. 2 is an external view showing toner cartridge I OOY according to the present exemplary embodiment, attached to toner cartridge docking unit 150Y. In the following description, to make the description easily understandable, X direction shown in the 30 drawing is referred to as forward direction, -X direction as backward direction, Y direction as right direction, -Y direction as left direction, Z direction as upward direction, and -Z direction as downward direction.

In the present exemplary embodiment, opening 115 takes the shape of a rectangle; however, opening 115 may take other shapes such as a polygon or an ellipse. A pair of guide members 114 is provided so that they sandwich opening 115. A guide member provided on the lower side portion of the right side surface of frame 20 member 1 1 protrudes in the right direction, and a guide member provided on the lower side portion of the left side surface of frame member 111 protrudes in the left direction. In the front side of frame member 111, there are provided projection portions 112, one of which protrudes in the right direction, and the other of which protrudes in the left direction, as shown in the drawings. Projection portions are examples of a 25 protective member for protecting side wall 122A or 122B (described later). Also, on the right side surface of frame member 11, arm-opening projection portion 113A is formed so that it protrudes in the right direction, and on the left side surface of frame member 111, arm-opening projection portion I 13B is formed so that it protrudes in the left direction. Arm-opening projection portions I 13A and I 13B are formed so that the 30 length in the horizontal direction becomes shorter from the back side to the front side, as shown in Fig. 7. Projection portions 112 are arranged so that the position in the vertical direction, as viewed from the front side, overlaps that of a part of side wall 122A or 122B, and - 13 does not overlap that of an end of bottom wall 121 (described later) of shutter 120, to prevent side walls 122A and 122B of toner cartridge 1 OOY which is being inserted, from coming into contact with members provided inside image-forming device 1. It is preferable that projection portions 112 are arranged so that the left tip does not protrude 5 relative to the left end of shutter 120, and the right tip does not protrude relative to the right end of shutter 120. Shutter 120 is a member for covering opening 115, which is roughly formed by bottom wall 121 which is an example of a covering portion for covering opening 115, guided members 123 which are examples of a supported portion which is supported by 10 guide member 114, side walls 122A and 122B, and back wall 122C which are examples of a connecting portion that connects bottom wall 121 and guided member 123. Bottom wall 121 is a wany rectangle plate, whose front end portion becomes thinner in the vertical direction toward the edge, and whose width in the horizontal direction becomes narrower toward the front side. 15 In the back side of bottom wall 121, back wall 122C is integrally formed so that it extends from bottom wall 121.

Opening member 165B includes two walls 164C and 164D which are integrally formed, and form an angle with each other. A dogleg formed by walls 164A and 164B points to the left, and a dogleg formed by walls 164C and 164D points to the right. (Operation of Attaching Toner Cartridge) 10 An operation of attaching toner cartridge IOOY to toner cartridge docking unit 150Y will be described with reference to Figs. 1 to 13. Fig. 11 is an enlarged view showing the front side of toner cartridge I OOY being attached to toner cartridge docking unit 150Y and the front side of toner cartridge docking unit 150Y. Fig. 12 is a diagram illustrating a positional relation between toner 15 cartridge docking unit 150Y and shutter 120 of toner cartridge 1 OOY positioned as shown in Fig. 11. Fig. 13 is a diagram illustrating a positional relation between toner cartridge docking unit 150Y to which toner cartridge 1 OOY is attached and shutter 120. When toner cartridge I OY is attached to toner cartridge docking unit 150Y, the front side of toner cartridge IOOY is inserted through the back side of toner cartridge 20 docking unit 150Y. After the front end of frame member Ill comes into contact with shutter fixing members 163A and 163B, if toner cartridge 1OY is further inserted into toner cartridge docking unit 150Y, the tip sections of shutter fixing members 163A bow outward as shown in Figs. 11 and 12. If toner cartridge 1 OOY is further inserted into toner cartridge docking unit 150Y, 25 left and right projection portions 112 of frame member I11 enter a space between salients 154A and 154B, and are guided in the forward direction by prevention plates 152A and 152B. Subsequently, the front sides of side walls 122A and 122B of shutter 120 enter the space between salients 154A and 154B, and shutter 120 moves between prevention plates 152A and 152B as toner cartridge I OY is inserted. 30 If toner cartridge IOOY positioned as shown in Figs. 11 and 12 is further inserted into toner cartridge docking unit 150Y, arm-opening projection portion 11 3A comes into contact with wall 164A of arm opening member 165A, and arm-opening projection portion 113B comes into contact with wall 164C of arm opening member 165B. If toner - 16 cartridge 1OY is further inserted, arm member 161A is bowed in the right direction by arm-opening projection portion 1 13A, and arm member 161 B is bowed in the left direction by arm-opening projection portion 1 13B. If toner cartridge IOOY is further inserted, the front end ofbottom wall 121 of 5 shutter 120 comes into contact with toner port forming member 151 D, and is fixed as shown in Fig. 13. Toner container 110 moves forward while leaving shutter 120 behind (shutter 120 moves relative to toner container 110), and moves to an open position at which opening 115 is exposed. If toner cartridge I OOY is housed in the housing unit, opening 115 faces toner port 153. 10 If arm-opening projection portion 113A is moved ahead of wall 164B of arm opening member 165A, and arm-opening projection portion 1 13B is moved ahead of wall 164D of arm opening member 165B, arm members 161A and 161B which have bowed outward straighten as shown in Fig. 13. As a result, shutter fixing member 163A hangs on the corner formed by side wall 122A and back wall 122C, and shutter fixing 15 member 163B hangs on the corner formed by side wall 122B and back wall 122C, whereby movement of shutter 120 is restricted. In a case where projection portions 112 are not provided, if toner cartridge lOY is inserted at a tilt in the horizontal direction, prevention plate 152A may come into contact with side wall 122A, prevention plate 152B may come into contact with side 20 wall 1228, or side walls 122A and 122B may come into contact with a member of the housing unit other than prevention plates 152A and 152B. As a result, shutter 120 may be moved to expose opening 115 while toner cartridge I OOY is being inserted, and toner may be leaked from opening 115. However, in the present exemplary embodiment, since projection portions 112 25 are provided ahead of side walls 122A and 122B, there is little chance that prevention plates 152A and 152B come into contact with side walls 122A and 122B. Accordingly, it is unlikely that shutter 120 is moved to expose opening 115 while toner cartridge I OOY is being inserted, and toner is leaked from opening 115. Also in the present exemplary embodiment, since, while projection portions 12 30 overlap the ends of side walls 122A and 122B in the vertical direction and the horizontal direction as viewed from the front side, projection portions 112 do not overlap the end of bottom wall 121 either in the vertical direction or the horizontal direction as viewed - 17 from the front side, toner port forming member 151 D is able to come into contact with bottom wall 121; accordingly shutter 120 can be moved relative to toner container 110. Also, in a case where the front sides of side walls 122A and 122B are not tapered, if toner cartridge 1 OOY is inserted at a tilt in the horizontal direction, prevention 5 plate 152A may come into contact with side wall 122A, prevention plate 152B may come into contact with side wall 122B, or side walls 122A and 122B may come into contact with a member of the housing unit other than prevention plates 152A and 152B. As a result, shutter 120 may be moved to expose opening 115 while toner cartridge I OOY is being inserted, and toner may be leaked from opening 115. 10 However, in the present exemplary embodiment, side walls 122A and 122B are in the horizontal direction tapered towards the front side to have a distance from prevention plate 152A or 152B. Specifically, side wall 122A is formed so that its outside surface opposite to the inside surface facing side wall 122B comes closer to the inside surface, and side wall 122B is formed so that its outside surface opposite to the 15 inside surface facing side wall 122A comes closer to the inside surface. Namely, the width of contact between the end of side wall 122A or 122B and prevention plate 152A or 152B is narrower than that in a case where side walls 122A and 122B are not tapered. Accordingly, there is little chance that side wall 122A or 122B comes into contact with prevention plate 152A or 152B. Also, it is possible to form the end of bottom wall 121, 20 which comes into contact with toner port forming member 151 D, widely, as compared with a case in which side walls 122A and 122B are not tapered. (Operation of Removing Toner Cartridge) An operation of removing toner cartridge IOOY from toner cartridge applied unit 150Y will be described. 25 When toner cartridge IOY being in the situation shown in Fig. 2 is pulled out from toner cartridge applied unit 150Y in the backward direction, since shutter 120 is fixed as shown in Fig. 13, components of toner cartridge I OOY other than shutter 120 are moved in the backward direction, and as a result, the lower side of frame member 111 is covered by shutter 120. 30 Arm-opening projection portion I 13A comes into contact with wall 164B of arm opening member 165A, and arm-opening projection portion 113B comes into contact with wall 164D of arm opening member 165B. In this situation, if toner cartridge I OY is further pulled out in the backward direction, arm-opening projection portion I 13A -18 causes arm member 161 A to bow in the right direction, and arm-opening projection portion 113B causes arm member 161B to bow in the left direction. As a result, the hanging on the corner formed by side wall 122A and back wall 122C by shutter fixing member 163A is released, and the hanging on the corner formed by side wall 122B and 5 back wall 122C by shutter fixing member 163B is released, whereby shutter 120 can be moved. After arm members 161A and 161B bow, if toner cartridge IOOY is further pulled out in the backward direction, back wall 122C of shutter 120 comes into contact with the end face of the back side of frame member Il l, and shutter 120 is moved 10 together with frame member 111. If toner cartridge I OY is further pulled out, toner cartridge I OOY is detached from toner cartridge applied unit 150Y. In summary, since shutter 120 is fixed until it covers the lower side of frame member 111, and is moved together with frame member 11 1 after the shutter covers frame member 111, opening 15 is not exposed while toner cartridge 1 OOY is pulled out. 15 Accordingly, it is prevented that toner flows anywhere other than into toner port 153. [Modifications] The above exemplary embodiment of the present invention may be modified as described below. In the above exemplary embodiment, image-forming device 1 may have not only 20 a copy function but also other functions such as a facsimile function, a scanner function of generating image data representing an image of a document read by reading unit 200, or a function of forming an image on a sheet in accordance with image data sent from a computer. Also, in the above exemplary embodiment, where the present invention is 25 described using toner cartridge I OOY, which is attached to/removed from an electrophotographic image-forming device, and stores powder toner to be used by a developing device, as an example, the present invention may be applied to other containers for storing supplies to be provided to a device. For example, if sealing performance of members around shutter 120 is enhanced, the present invention may be 30 applied to a container for storing liquid developer. Alternatively, the present invention may be applied to a container for storing ink to be provided to an ink-jet image-forming device.

- 19 Also, in the above exemplary embodiment, where side walls 122A and 122B are tapered so that the slope of the tapered wall is linear, as shown in Fig. 5, the slope may be curved. Also, in the above exemplary embodiment, where side walls 122A and 122C of 5 shutter 120 are integrally formed, and side walls 122B and 122C of shutter 120 are integrally formed, side wall 122C may be formed as a member separated from side wall 122A or 122B. Also, in the above exemplary embodiment, where the front side of side walls 122A and 1228, and bottom wall 121 of shutter 120 are tapered, side walls 122A and 10 122B, and bottom wall 121 do not have to be tapered, as shown in Figs. 14A and 14B. Also, in the above exemplary embodiment, the length in the horizontal direction of projection portions 112 may be shorter than that of projection portions 112 shown in Fig. 4, as shown in Fig. 15, as long as projection portions 112 are able to prevent the front side of side walls 122A and 122B from coming 15 into contact with salients 154A and 154B. Also, in the above exemplary embodiment, contact between the front end of shutter 120 and salient 154A or 154B may be prevented without using projection portions 112. For example, instead of projection portions 112, columnar protection portions 20 116 that protrude in the downward direction from toner container 110 as shown in Fig. 16 may be provided in front of frame member 111. Columnar protection portions 116 may be provided as shown in Fig. 17, if shutter 120A shown in Fig. 14 is used instead of shutter 120. If shutter 120A is used, alternatively, columnar protection portions 116 may be 25 provided on either side of frame member 111, as shown in Fig. 18. It is to be noted that the front side of protection portions 116 shown in Figs. 14 to 18 may be tapered, and the width in the horizontal direction becomes narrower toward the front side, as in the case of shutter 120. Also, in the above exemplary embodiment, where the housing unit includes 30 prevention plates 152A and 152B, and salients 154A and 154B, and where projection portion 112 is provided on either side of frame member 111, only prevention plate 152A and salient 154A may be provided, and projection portion 112 may be provided on only the right side of frame member 11. Alternatively, only prevention plate 152B and - 20 salient 154B may be provided, and projection portion 112 may be provided on only the left side of frame member I11. Also, in the above exemplary embodiment, where toner cartridge IOOY has projection portions 112 as shown in Fig. 4, toner cartridge I OOY does not have to have 5 projection portions 112 as shown in Fig. 19. The foregoing description of the exemplary embodiments of the present invention has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously, many modifications and variations will be apparent to practitioners skilled in 10 the art.
